What is 1:30 leverage and why did ESMA introduce it?

On the first of August 2018 every regulated broker in the European Union had to cut leverage for retail clients to 1:30 on major pairs, almost overnight. The decision came from ESMA, the European Securities and Markets Authority, after data gathered across fourteen countries showed that somewhere between 74 and 89 percent of retail accounts were losing money. This was never a broker's marketing choice or a single national whim — it was a shared European safety brake. In this article I explain where the number 1:30 actually came from, how the cap works in practice, and what it means for an account held under a national regulator such as the Polish KNF.

What did ESMA actually change on the first of August 2018?

Formally this was ESMA Decision (EU) 2018/796 on temporary product intervention measures relating to contracts for difference (CFDs). The word "temporary" matters — the measures originally ran in three-month windows and had to be renewed every quarter. When ESMA stopped extending them in 2019, national regulators did not roll the rules back. Quite the opposite: Poland's KNF, Germany's BaFin and France's AMF reintroduced identical requirements as permanent national law. So since 2019 a Polish retail trader operates on exactly the same terms as a German or a Spanish one, even though the formal legal basis is now a national decision rather than the ESMA measure itself.

Leverage was the loudest part of the package, but it was not the only limit. The ESMA cap is tiered by asset class — the more volatile the instrument, the lower the leverage allowed.

On top of that came three protections that work independently of leverage. The first is mandatory negative-balance protection — the broker cannot demand more than you actually deposited, even if the market opens with a violent gap. The second is a compulsory margin-close-out once the protection level falls to 50 percent of required margin. The third is a standardised risk warning in which the broker must publish its own current percentage of losing accounts. Together with a ban on deposit bonuses this forms a coherent package — it was never only about leverage, but about the entire shape of retail trading conditions.

Why exactly 1:30, and not 1:50 or 1:10?

The number did not fall from the sky. Before ESMA reached for intervention, national regulators pooled data from retail accounts covering roughly 2015 to 2017. The picture was unambiguous and sobering: on the large majority of accounts clients lost money, and the higher the leverage on offer, the higher the loss rate turned out to be. At leverage around 1:400 or 1:500 the share of losing accounts climbed into the low nineties percent. It was precisely this relationship — more leverage, more losses — that became the central argument for a hard limit.

The value of 1:30 is a deliberate compromise. At 1:1, CFD trading would stop differing from buying the currency outright and the product would lose its purpose; at 1:200 the problem of excessive losses would have continued. A cap of 1:30 means required margin of 3.33 percent of position value — low enough that a small investor can still trade mini and micro lots, yet high enough that a single nervous market swing cannot zero an account in minutes. After the cap the share of losing accounts fell, but it did not vanish — in the following years it kept running between 74 and 89 percent. The lesson is plain: leverage is only one factor, and the rest is position size and trader psychology.

"The new measures will provide retail investors with better protection by reducing the risks associated with these complex products." — Steven Maijoor, ESMA Chair, statement on product intervention measures for CFDs, 2018.

How does the ESMA cap compare with other markets?

Leverage limits are not global — they are regional, and any trader reading English-language forums should keep that in mind. Rules that look like a "market standard" in fact apply only within a given jurisdiction.

The British FCA copied the ESMA rules almost word for word in its policy statement PS19/18 from 2019 and kept them even after the country left the Union. Australia's ASIC followed with an identical cap in 2021. The United States is the outlier — the American CFTC keeps 1:50 on major pairs, the highest limit among large regulated markets, arguing that its market is more mature. The retail-loss data does not strongly support that claim, but such is the legal position. The practical takeaway for a European trader is simple: when you see an advert promising "1:500 leverage, regulated broker", check carefully which regulation is meant. More often than not it hides an offshore entity — Vanuatu, Saint Vincent or Belize — or an offer aimed at professional clients.

What does the 1:30 cap mean in practice for your deposit?

The most tangible consequence is that the same position size now requires much more margin. The margin requirement is simply the inverse of leverage — at 1:30 it works out to 3.33 percent of contract value. The gap between the ESMA cap and an offshore offer is enormous, which is why low leverage is so often mistaken for a drawback.

Opening a full lot of EUR/USD at a regulated broker therefore ties up 3,333 USD as margin. In practice a small investor rarely trades a full lot — more often micro or mini lots, so realistically the requirement comes down to tens or a few hundred dollars. I unpack the mechanics of that block and the difference between leverage and margin separately in the piece on how leverage differs from margin, because it is one of the most frequently confused pairs of terms on the market.

The second effect is less obvious but more important: the cap protects you from yourself. Combining a 1:30 limit with a sensible per-trade risk rule keeps your maximum position much smaller and your margin for error larger. The third effect is negative-balance protection — even if the market opens with a brutal gap, as it did after the Swiss National Bank decision in January 2015 or the Brexit referendum in June 2016, you will not receive a chase letter demanding more than your deposited capital. From two decades of watching this market I know that 1:500 sounds tempting to a beginner, because it asks for almost nothing up front. Yet that very temptation — a low entry threshold combined with a high risk of ruin — is the fastest route to losing an entire deposit during the first months of learning.

Professional-client status — is giving up protection worth it?

The ESMA cap applies to retail clients only. An investor can ask the broker to reclassify them as a professional client and so regain access to higher leverage, reaching as far as 1:500. It sounds attractive until you read the other side of the contract. To gain that status you have to meet at least two of three conditions: carry out significant transactions at a meaningful frequency over the last four quarters, hold a financial portfolio above 500,000 euro, or have at least one year of professional experience in the financial sector in a role that demands knowledge of these products. What you gain and lose under each category is spelled out in the comparison of retail, experienced and professional client classifications.

The price of the switch is real. A professional client loses statutory negative-balance protection, loses the standardised risk warnings and — most importantly — in many cases loses access to investor-compensation schemes should the broker fail. In other words, you hand back precisely the safeguards ESMA introduced in exchange for more leverage. For an experienced investor with substantial capital that is sometimes a reasonable trade; for a beginner trying to "get around" the 1:30 cap it runs in the opposite direction to safety. Professional status is not a shortcut to bigger gains — it is the surrender of a protective umbrella.

What to do after you close this page

1. Check your own leverage inside the platform. In MetaTrader right-click EUR/USD, choose Specification, and find the "Margin Initial" field. For a retail client in the European Union it should read roughly 3.33 percent, which corresponds to 1:30 leverage. If you see 0.2 percent you are on 1:500, and you should immediately clarify on what basis your account is being run.
2. Verify your broker's licence in the regulator's register. Open your national regulator's website, find its register of authorised investment firms, and type in the broker's name. If it is not there, check the public-warning list as well — it takes two minutes and can save an entire deposit. The regulations section walks through how to read these registers.
3. Work out the required margin for your typical position. Take the size you usually open, divide the contract value by 30, and write the result down. That way you enter the market knowing exactly how much capital the broker will lock up, instead of finding out only when a margin call arrives.
4. Think hard about your client status before clicking "professional". If a broker offers higher leverage in exchange for reclassification, read carefully which protections you are giving up, and weigh that against the underlying concept of leverage and what it really does to your downside.
